Definitions

  • the invention relates to an actuating device for clamping or for machining workpieces or for clamping wires according to the preamble of claim 1.
  • Such actuators are known in the art as clamping cylinders or punches.
  • pressure forces are generated by means of pneumatically or hydraulically actuated piston, which act directly on a push rod as a drive element, through which then the workpiece is pressed against a counter stop surface and thus held stationary or processed.
  • This can, for example, the EP 1 264 659 B1 be removed.
  • a clamping iron or a punching tool is attached, so that caused by the resulting pressure forces holding forces or deformations on or in a workpiece made of metal.
  • the existing pressure force is dependent on the geometric configurations of the piston and the set pressure state; the larger, therefore, the acting piston surface is configured, the greater pressure forces can be transmitted to the push rod.
  • a toggle lever device in particular for use in the bodywork of the automotive industry, refer to, which has a housing in which a piston rod is held linearly movable. One of the ends of the piston rods is connected to a toggle lever; whereas the other opposite free end of the piston rod is inserted into a pressure space whose volume is variable.
  • a clamping arm is mounted through which a workpiece is clamped.
  • the pneumatically or hydraulically generated force of a drive element for example a piston of a manually operable spindle or the like is transmitted by means of the toggle lever on the pull rod and characterized in that the pull rod on the housing on the opposite end to the articulation of a lever arm of the toggle lever the pull rod passes through, a force deflection is achieved, by which the compressive force generated by the drive element is converted due to the deflection in a tensile force, so that no rotations arise between the toggle lever and the tie rod. Rather, the power flow is in two mutually parallel planes, whereby the force generation, the power transmission and the introduction of force between the tie rod and the workpiece is mechanically defined calculated.
  • a drive element for example a piston of a manually operable spindle or the like
  • a tool for example in the form of a clamping iron or in the form of a punching tool, attached to the tie rod and when the pull rod is rotatably mounted in the housing, because the tool can be both pivotable and linear deliverable in the direction the workpiece are delivered, so that for equipping a machine tool attached to the pull rod tool can be removed from the working area of the machine tool so that this area is freely accessible.
  • the tool is first deliverable pivotable in the direction of the workpiece without a force between the workpiece and the tool is present. Only when an effective contact between the tool and the workpiece is formed, the linear delivery of the tool takes place in the direction of the workpiece, because in the pull rod an actuating groove is incorporated, which consists of two sub-areas.
  • the first portion extends parallel to the longitudinal axis of the tie rod and the second portion is inclined or helically aligned with respect to the longitudinal axis of the tie rod.
  • In the actuation groove projects a guide pin or a ball, which is attached to the housing or.
  • a plurality of such toggle can be arranged in the housing in different aligned planes, so that several tie rods are synchronously actuated to each other, without the need for additional drive elements are provided, because the arranged laterally next to the guide plate drive elements can move a correspondingly designed guide plate such that in this more of the nodes of a toggle lever are used in different levels, whereby the pull rod, which is individually connected to each toggle lever, is movable back and forth.
  • the transmission ratio of the toggle lever can also be converted such that the force profiles predetermined by the toggle lever can be adjusted to the respective machining process or application of the actuating device.
  • the toggle usually has over the stroke on an exponentially extending force curve, in the nearly spread state of the toggle lever based on the distance traveled, the largest slope has.
  • a force curve can be changed by the cam, so that the toggle, for example, a nearly constant force during the clamping or machining process on the pull rod exerts.
  • a center position or rest in the control groove may be provided to a Vigel by which the Stak is held on a mast of a sailboat, can be partially opened, whereby the clamping forces are reduced to the Want.
  • This is required in the winter storage of the sailboat or during sailing as strain relief of the so-called Leewant to make new settings.
  • a force adjustment takes place nevertheless by means of different courses of the control grooves in the guide plate, without the pressure conditions in the drive elements to be changed
  • FIG. 1 an actuator 1 can be seen, through which a workpiece 12 is machined by means of a punching tool 13 which rests against a counter-stop 34.
  • the actuating device 1 consists of a housing 2, whose longitudinal axis is designated by the reference numeral 3.
  • two pistons 5 and 6 are provided in the housing 2, which are each hydraulically or pneumatically by means of a controller 7 back and forth by means of pumps 9 movable.
  • the hydraulic or pneumatic media are conveyed through lines 8.
  • the controller 7 is operated to reciprocate the pistons 5 and 6. It is also conceivable to accomplish the drive by means of only one piston 5.
  • the pistons 5 and 6 can act either double or single. As a further drive elements manually operable spindles, levers or other devices can be used by the compressive forces can be generated.
  • a pull rod 10 is mounted axially displaceably in the housing 2; the longitudinal axis of the tie rod 10 is provided with the reference numeral 10 '.
  • the pull rod 10 passes through a through opening 11 incorporated in an end face 4 of the housing 2, so that the pull rod 10 projects partially outwards and at the free end of which the tool 13 is attached.
  • the pull rod 10 is connected via a toggle lever 21 drivingly connected to the two pistons 5 and 6.
  • the toggle lever 21 consists of two mutually articulated lever arms 22 and 23, whose common node is designated by the reference numeral 24.
  • the first lever arm 22 is rotatably hinged to the pull rod 10 and the second lever arm 23 rotatably connected to the housing 2.
  • the articulation points between the respective lever arm 22 and 23 are provided with the reference numerals 25 and 26, respectively.
  • the articulation points 25 and 26 lie in the plane of the center axis of the passage opening eleventh
  • the node 24 of the toggle lever 21 is inserted into a control groove 16 incorporated in a guide plate 15.
  • the two pistons 5 and / or 6 are positively connected with double-acting cylinder and force fit with single-acting cylinder with the guide plate 15, so that the guide plate 15 is moved linearly back and forth by the movements of the piston 5 and / or 6.
  • the pistons 5 and 6 are arranged in alignment with each other on a parallel to the longitudinal axis 10 'of the tie rod 10 extending axis, so that the force is applied to the guide plate 15 parallel to the longitudinal axis in the tie rod 10.
  • the contour of the cam groove 16 is wave-shaped in the embodiment shown and oriented relative to the longitudinal axis 15 'of the guide plate 15 inclined. Any desired inner contour is optionally usable, depending on the desired transmission ratio for power transmission between the toggle lever 21 and the pull rod 10.
  • the node 24 is actuated due to the contour of the cam 16 such that the two lever arms 22 and 23 are spread, until such time as a nearly 180 ° position , thus forming a common axis, have reached.
  • the second lever arm 23 is supported on the housing 2, the articulation point 25 of the first lever arm 22 moves to the right.
  • the housing 2 is provided with such a large space to be dimensioned that thereby the linear movement of the drawbar 10 is not hindered.
  • the tie rod 10 is guided in the region of the articulation point 25 from an incorporated into the housing 2 opening to the outside.
  • the piston 6 is actuated and thus presses on the guide plate 15; the piston 5 is released, so that the guide plate 15 is displaced to the right without counterforce, so that the node 24 is raised from the spread position along the inner contour of the cam 16, whereby the pull rod 10 is moved away from the workpiece 12.
  • the actuator 1 is used as a holding or clamping device.
  • a clamping tool 13 in the form of a clamping iron is attached to the drawbar 10, by which the workpiece 12 is clamped to the counter-stop 34.
  • the reference numeral 35, the clamping surface of the workpiece 13 is marked.
  • an actuating groove 18 is incorporated in this, which consists of a first and a second portion 19 and 20 respectively.
  • the first portion 19 extends parallel to the longitudinal axis 10 'of the tie rod 10 and the second portion 20 bends obliquely from the first portion 19 from.
  • the second portion 20 may also be designed helically inclined.
  • a guide pin or a ball 32 is provided in the housing 2, the free end of which engages in the actuating groove 18.
  • the pull rod 10 is rotated by the guide pin or ball 32 and the oblique arrangement of the second portion 20 of the actuating groove 18 about its own longitudinal axis 10 ', so that the tool 13 is delivered in the direction of the workpiece 12 to be clamped pivoted.
  • the guide pin or ball 32 is immersed in the linear portion 19 of the actuating groove 18, there is no rotation of the tie rod 10, but there is exclusively a linear or axial delivery of the tie rod 10 in the direction of the workpiece 12 to be clamped.
  • the workpiece 12 is therefore braced between a clamping surface 35 of the tool 13 and the counter-stop 34.
  • a circumferential groove 30 is incorporated in this.
  • a patch on the pull rod 10 sleeve 29 has a wedge 31, pad or the like, which is inserted in the assembled state in the groove 30. Consequently, the rotation of the drawbar 10 about its own longitudinal axis 10 'is not blocked, because a rotational movement between the tie rod 10 and the sleeve 29 supported on the first lever arm 22 can take place. It is also conceivable to clamp the sleeve 29 between a Segering 28 and an integrally formed on the tie rod 10 stop collar 27, so that it is held in the axial direction.
  • the lifting point 25 thus serves as a radial support for the sleeve 29, which is rotatably connected thereto. Thus, a relative movement, namely a rotation, between the sleeve 29 and the tie rod 10 arise.
  • FIG. 3 shows the application of the actuator 1 as a turnbuckle on a Stak for a sailboat mast.
  • the actuating device 1 is thus installed between a hull and the shroud shown schematically.
  • the opening and closing of the actuator 1 is done manually via a lever 37, which is for example eccentrically connected to the guide plate 15. But it is also a direct Kraftanlenkung the lever 22 and / or 23 conceivable.
  • the cam groove 16 has an intermediate position 17, in which the node 24 is held stationary as long as the lever 37 is not actuated.
  • the tensile forces prevailing in the sheath can thereby be reduced in order to reduce the tensions between the mast and the hull. This is required in the winter storage of the sailboat or during sailing as strain relief of the so-called Leewant to make new settings.
  • the lever 37 can be closed in a simple and fast manner, so that the node 24 is transferred from the intermediate position 17 in an end or in a starting position , whereby either the Want is completely stretched or relieved.
  • the actuator 1 is reconstructed in the form that three tie rods 10 are mounted in the interior of the housing 2 parallel to each other and axially displaceable.
  • a tool 13 in particular for clamping the workpiece 12, is actuated.
  • Each tie rod 10 is connected via the one toggle 21 with the guide plate 15, which has a triangular cross-sectional contour in the embodiment shown.
  • the guide plate 15 has a triangular cross-sectional contour in the embodiment shown.
  • one of the control grooves 16 is incorporated, in each of which one of the nodes 24 of the bell crank 21 is inserted.
